CONNECTING MEANS FOR SPRINGS.

Application filed August 5,1924.

This invention relates to means for connecting spacer springs to the main upholstery springs in structures such as are described in Hunt Patent No. 1,027,051.

By our invention weprovide a means for attaching the spacer springs so that these springs are locked firmly in place without the use of tools.

In the accompanying drawings which show illustrative examples of our invention, Fig. l is a plan view of a portion of an upholstery spring with two spacer springs attached to it. This view merely shows the position of the connection; Fig. 2 is a side view of a spacer spring adapted for use with our invention; Fig. 3 is an end view thereof; Fig. 4 shows a side view of the connecting member in place on the upholstery spring; Fig. 5 is an end view of. the same parts; Fig. 6 is a side view of the parts shown in Figs. 2 and 4 in their attached position; Fig. 7 is a corresponding end view; Fig. 8 shows another side View taken from a different angle from that shown in Fig. 6; Fig. 9 shows a modified form of the device shown in Fig. l, and Fig. 10 shows the device of Fig. 9 in place and also shows other possible modifications.

In carrying out our invention, the end of the spacer spring 2 is bent back upon itself as shown at- 3 in Fig. 3, but this bent back end projects slightly beyond the end of the spring 2 as shown in Fig. 2. Just at the beginning of the second turn of spring 2, the spring is deformed by forming a loop 4 which extends back: towards the body of the spring 2.

The connecting member 5 has a central loop 6 and two portions 7 and 8 respectively which are intended to engage the first turn of the spring 2. The ends of the attaching members 6 may be bent to any desired position, but should be so bent that they cannot catch on a mattress or the like. In Figs. 4: and 5 the lower end is shown as bent around toform a closed loop which lies in the same plane as the loop 6, whereas, the upper end is bent substantially at right angles to the plane of the loop 6 so that it will extend along one of theturns of the spring 2 and then turns in towards the axis of spring 2. In Fig. 8 the upper end is shown as bent to form a closed loop 8 sim- Serial No. 730,206.

ilar to the lower loop which has been deuntil the end 3 passes behind the abutting portion 8 of member 5 and down between this abutting portion and the outer surface of upholstery spring 6. As the rotation is continued the bent out end 3 will pass down beyond the outer edge of upholstery spring 6 and as soon as this end has passed below the upholstery spring it will snap into place as shown in Fig. 6. This will prevent spring 2 from being removed by a counter-rotation. At the same time, it will be noticed, as shown in Fig. 6, that loop 4 has come into contact with abutting portion 7 of attaching member 5 and will prevent the spring 2 from being rotated any further in the original direction; thus spring 2 is held firmly locked against spring 9. It is also to be noted that this attaching member 5 contacts with spring 2 at two points and it is desirable that the abutting portions 7 and 8 be. so located that the spring 2 will press against upholstery spring 9 at two points, as this will tend to prevent the spring 2 from slipping out of its proper position.

In Fig.9 I show a modified form of device in which the bent back portion 3 of spring 2 is made of sufiicient length so that it will contact both with the upholstery spring 9 and with the lower portion of attaching member 5. This arrangement, as well as the one previously described, will prevent the spring 2 from being rotated in either direction.

It is to be understood that the foregoing examples are given by way of illustration only and that many modifications may be made in the details of the device without departing from the spirit of our invention.

What we claim is:

1. An upholstery spring, a connecting member adapted to engage the upholstery spring and having a bearing point adapted holstery spring, a spacer spring having an end portion adapted to be brought into compression between said bearing point and the upholstery spring by rotation of the spacer spring, and a latch on the spacer spring adapted to engage the upholstery spring to prevent the spacer spring from rotating in a reverse direction and separating from the upholstery spring.

2. A device as defined in claim 1 further characterized by having means for limiting the forward rotation of the spacer spring so that the same cannot be rotated substantially beyond the point where the latch engages the upholstery spring.

3. A device as defined in claim 1 further characterized by having means for limiting the forward rotation of the spacer spring so that the same cannot be rotated substantially beyond the point Where the latch engages the upholstery spring, said means being provided by a distortion of the spacer spring so placed as to engage a bearing point of the attaching member.

4:. In combination, an upholstery spring having all of its top ring, except the tip thereof, following a substantially even curve, a spacer spring, and an attachment member having a loop which engages the upholstery spring and having two bearing surfaces each of which engages a portion of the same turn of the spacer spring and holds such portion pressed against the periphery of the upholstery spring so that the spacer spring is pressed against the upholstery spring at two points on the outside of said substantially even curve, and means for liniiting rotation of the spacer spring relative to the upholstery spring.
